Disruption to the life-cycle of the blackhead parasite is the best way to reduce the impact of the disease. Increasing the turnover of epithelial cells lining the intestinal wall means that the parasites are shed before they have the opportunity to reproduce, penetrate the gut lining and migrate to the liver and caecum where they would usually cause lesions.
I've used this product for a few months now I have seen so much improvement in the young birds without the expensive treatment lines I use all three products that are available with a small amount used each day it is very economical and being Natural I believe it is a lot better for the birds
Don't have any problems with birds drinking it haven't noticed any great difference in birds themselves but might be too soon for that.
I breed show budgies and you could see the improvement in the birds.But supply needs to be more reliable waited 3 months to get last order .
